The EEA is to report that the amount of HFC refrigerant placed on the market in 2015 – the first year of the phase-down mechanism – was within the quota allowance.

Russian retailer Magnit opened a new supermarket featuring a CO₂ transcritical refrigeration system manufactured and installed by NORD-SM with UNIDO technical support.

The book Refrigeration – Solved Examples is intended as a reference book for practicing engineers who would appreciate having a summary of useful formulae made available to them. It should serve as useful supplementary reading to students at various academic levels, lecturers and research workers.

Heat exchanger, tied to the U-Turn NH₃ separator, to serve growing market for cascade systems.

Ice plant installer Vink sees CO₂ systems as the cheapest available option for light industrial applications like in the fishing sector.

I was going to call this post “Playing With Fire” but didn’t for obvious reasons. Anyways, in my last post we saw how CO₂ (R744) can be used in both a traditional sub-critical as well as in trans-critical cycles which operate almost backwards to each other. Also, when I typed in trans-critical without the hyphen, Spell Wreck asked me if I meant to type ‘transatlantic’ instead. Um no, but it did remind me of a little bit of history to touch on before we move onto R290. I apologize for the digression but I think you will find it interesting.

The growing popularity of “natural” refrigerants has prompted A-Gas to add ammonia to its UK product range.

Researchers working for the Montreal Protocol-funded PRAHA project found that R290 air-conditioning has a higher cooling capacity and is more energy efficient than HFCs.

“The use of natural refrigerants [like ammonia] is probably more prevalent in breweries than in most industrial or commercial refrigeration plants,” said Mark Bulmer (global segment manager (cooling), GF Piping Systems) at BrauBeviale an international beverage trade fair taking place in Nuremberg, Germany on 8-10 November.

His campaign statements suggest the EPA’s HFC restrictions could be slowed down, impacting CO₂ uptake, but industry support of the Kigali Amendment could make HFCs a low priority.

Hydrocarbons are expected to replace HFCs R404A and R134a in beer fridges the world over.

The Swedish transcritical CO₂ supplier sees the U.S. food retail sector turning towards natural refrigerant systems.

Eurocold recently installed a CO₂ system with parallel compression at a Recheio store in Torres Novas, Portugal.

Investigators have so far refused to confirm or deny whether the refrigeration system was the source of yesterday’s fatal ammonia leak at the Carlsberg brewery in Northampton.

A combination of the HFO refrigerant 1234ze and “natural” refrigerant CO₂ is providing all the ac and refrigeration requirements of a retailer in Brno (CZECH REPUBLIC).

Propane (R290) boasts superior heat transfer potential than R32, R1234ze and a combination of R32 and R1234ze, according to a recent paper from the University of Padova, Italy.

The Institute of Refrigeration and A-Gas is hosting another free breakfast briefing, this time on the subject of new refrigerants.

Johnson Controls’ chiller and heat pump units use no more than 49 kg (108 lbs.) of ammonia.

As part of the Kigali agreement to phase-down HFCs, under the Montreal Protocol, China is proposing a review of safety standards to remove barriers to alternatives to HFCs, especially natural refrigerants.
